Artifactory可以使用Groovy脚本实现浏览多层Zip包的内容。下面是一个代码示例：

import java.util.zip.*
import org.apache.commons.io.IOUtils

def archive = new ZipFile('path/to/your/multilevel/archive.zip')
def entries = archive.entries()

while (entries.hasMoreElements()) {
    def entry = entries.nextElement()
    if (!entry.isDirectory() && entry.name.endsWith('.zip')) {
        def innerArchive = new ZipInputStream(archive.getInputStream(entry))
        def innerEntries = innerArchive.entries()
        while (innerEntries.hasMoreElements()) {
            def innerEntry = innerEntries.nextElement()
            // Do something with the inner entry, e.g. print its name
            println(innerEntry.name)
        }
    } else {
        // Do something with the outer entry, e.g. print its name
        println(entry.name)
    }
}

上述代码会遍历指定路径中的所有Zip包，并输出它们的内容。其中，如果Zip包为多层Zip包，则会进一步遍历其内部Zip包的内容。
